r^-4s^-2 r = -3 s = 5

OpenStudy (anonymous):

\[r ^{-4}s ^{-2}\]

HanAkoSolo (jamierox4ev3r):

wait… would the original look like \[r ^{-4} s ^{-2}\] ?

HanAkoSolo (jamierox4ev3r):

lol never mind i just realized something…disregard that :P

HanAkoSolo (jamierox4ev3r):

so just plug in the values… \(-3^{-4}\) \(5^{-2}\)

HanAkoSolo (jamierox4ev3r):

and solve from there :) do you still need help? @elliecosme ?

OpenStudy (anonymous):

1/(-9)(25) ?

OpenStudy (anonymous):

Well from the website they changed it to simpler way but kinda still gets me confused.

HanAkoSolo (jamierox4ev3r):

okay np :)

HanAkoSolo (jamierox4ev3r):

so for negative square roots… you would go back decimal places, not whole values (this is not absolute value).

HanAkoSolo (jamierox4ev3r):

so think of it as standard form: \(-3^{-4}\) = 1/81…because \(3^4\)=81, and \(-3^{-4}\) is the fraction form of it because of the negative exponent

HanAkoSolo (jamierox4ev3r):

Does that make more sense?

OpenStudy (anonymous):

Oh yeah, I'm catching on.

HanAkoSolo (jamierox4ev3r):

:D okay good lol teaching has never been strong for me.. I'm working on it :P do you think you can solve the next one?

OpenStudy (anonymous):

5^-2 1/25 ?

HanAkoSolo (jamierox4ev3r):

yeah that's right! :DD

HanAkoSolo (jamierox4ev3r):

nice one ^_^ *internet high five* let me know if you have questions…and for now, have a nice day

OpenStudy (anonymous):

Wait sorry I don't exactly know how to put that as an answer though for r^−4s^−2

OpenStudy (anonymous):

@Jamierox4ev3r

HanAkoSolo (jamierox4ev3r):

you would put the final simplified form :) so what are the two fractional values that you got?

OpenStudy (anonymous):

1/81 and 1/25

HanAkoSolo (jamierox4ev3r):

mhm…so how would you combine those together, since they are like terms?

HanAkoSolo (jamierox4ev3r):

yikes…that may take a while

HanAkoSolo (jamierox4ev3r):

find the lcd, and make the needed changes...

OpenStudy (anonymous):

Oh well I forgot to write down what I got but I got 25/81
